Question

我有一个表格，其中有4列表格名称：充值

------------------------------------
Status | Adjustment | Kisok | Done  |
 Yes   |   232      |  Abc  |  ok   |  
 NO    |  Null      |  Adc  |  No   |
-------------------------------------

我希望状态=是当调整，Kisok和完成不为空时如果状态=否然后Adjustment，Kisok和Done可以同时为null和Not null

我希望使用算术SQL查询（和（或））中的此查询如果不大小写，如果还可以如果您能帮助我，那我很好

我知道Logic很好，但是我不清楚语法

此查询有误>>

SELECT Status1,csdoneby,kioskdoneby,adjtmentstype,
   (CASE
    WHEN csdoneby,kioskdoneby,adjtmentstype, IS NOT NULL THEN Status1='yes'
    ELSE Status='No'
END as Test)
FROM topup;

Answer 1

您应将条件分配给每一列

SELECT Status1, csdoneby,kioskdoneby, adjtmentstype,
   CASE
    WHEN csdoneby IS NOT NULL 
        AND kioskdoneby IS NOT NULL 
        AND adjtmentstype IS NOT NULL THEN 'yes'
    ELSE 'No'
END as Test
FROM topup;

Answer 2

这是正确的语法。

SELECT 
Status1,
csdoneby,
kioskdoneby,
adjtmentstype,
CASE
    WHEN csdoneby IS NOT NULL
         AND kioskdoneby  IS NOT NULL
         AND adjtmentstype  IS NOT NULL
      THEN Status1='yes'
    ELSE 'No'
END as Status
FROM topup

Answer 3

尝试这样

SELECT Status1, csdoneby, kioskdoneby, adjtmentstype,
       CASE WHEN csdoneby IS NOT NULL AND kioskdoneby IS NOT NULL AND adjtmentstype IS NOT 
       NULL THEN 'yes'
       ELSE 'No'
       END AS Test
FROM topup;

我需要算术SQL查询
